Development of a real-time track reconstruction for the proposed LumiTracker detector — Johannes Albrecht, Lukas Calefice, Elena Dall’Occo, •Lukas Rolf, and Holger Stevens — Experimentelle Physik 5, TU Dortmund

Measuring the luminosity is a vital task performed at the LHCb experiment. The luminosity is used as feedback for the LHC and as input for many analyses. The main goal of the proposed LumiTracker detector is to provide a measurement of luminosity by operating independently from the rest of the LHCb experiment. The LumiTracker measures luminosity by reconstructing and counting tracks and to provide an online measurement of luminosity per bunch every few seconds, the reconstruction needs to be performed in real-time. This contribution will present the current status of the pattern recognition and track fitting algorithms developed. The overall performance of the track reconstruction will be compared between a CPU and a GPU implementation, with the latter bringing the advantage of greater parallelism.
